On the evening of May 13, 2016, my husband and I boarded a First Class train carriage to Manchester from London Euston. We heard the ladies before we saw them, as the group of three, aged between 35 and 55, rolled up the aisle laughing hysterically and demonstrating every gulp of wine they had clearly spent the afternoon mistaking for water and solids. As they settled at the table in front of us we were thankfully invisible to them, but they were giving the train crew a particularly hard time.
